477 pretend there's a static mapping here.
478 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
479 function to get the register name. That ought to be accurate.
480 However, we're changing a compile-time dependency (using the
481 REGISTER_NAMES macro) into a link- and run-time dependency
482 (calling REGISTER_NAME, which happens to be a function call on the

515 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
517 * table.c (table_open): For cygwin hosts, we need to use the
518 return value from the read routine as the number of bytes to
519 process. This apparently is due to text-mode vs binary-mode. If
520 the mounts are done text-mode, then the size returnedby fstat()
521 may be different than the number of bytes "read" in text mode.

548 * Makefile.in: The run target depended on a target psim$(EXEEXT),
549 but there was no such target, only plain psim. So I changed the
550 run target to depend on psim.

554 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

958 determine the simulation speed by looking at the number of elapsed
959 ticks recorded by the event queue.
961 * psim.c (psim_write_register, psim_read_register): Force the cpu
962 to zero when it is either of `-1' or `nr_cpus'. In both cases the
963 next cpu would be zero any way.
965 * mon.c (mon_print_info): If possible, print the system cycle
966 performance. This is an indication of the number of instructions
969 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
971 * The code to allow an event queue to be updated during a signal
972 was missing. For main.c, a cntrl-c simulation termination wasn't
975 * The simulation would not correctly restart if an event requested
976 that the simulation be halted.
978 * psim.c (psim_options): Add hack to -i option to optionally
979 include a level vis -i2.
980 (psim_usage): Document.

999 * gen-idecode.c (print_run_until_stop_body): Call
1000 event_queue_process_events to clear possibly pending events before
1001 starting a simulation run. Re-arange main loop so that simulator
1002 is correctly restarted when an event halts the simulation.

2605 * configure.in: New option --enable-sim-line-nr (default enabled).
